Hi everyone, just a little curious on what side of the old "metaphorical" coin my phone has fallen on. The problem this coin is concerning, is simply one related to my SIM. My phone has no cell service right now since it doesn't want to acknowledge or use the sim card it has in it. It's a 512Gb unlocked phone I special ordered upon first release, no other problems (other than the screens scratching easily) but now it's no longer working on anything other than wifi. It's the wifi that I think caused this problem actually. I just set up a new lightweight Asus RT-AX56U router to utilize two WAN ports (one built in and the other setup through a USB ethernet adapter). The problem came about after I switched down to a WPA3/WPA2 setup from a full WPA3 simply due to a connection problem one of my laptops was having (it's wifi card was one from prior to WPA3). Shortly after I did that my Z Fold 3 started having frequent wifi drop problems. After about an hour of that the connection seemed stable, then the next thing I know the phone dropped connection to both Wifi and cell network! Then after I restarted the router, only wifi would reconnect and my cell network connection has been M.I.A. ever since despite what I do (tried airplane mode, tried cache whipping it, restarting it, and finally even a full factory wipe/restart). My phone is up to date on all of it's updates (finally decided to last month after seeing that my model has no root + camera options) but nothing other than a routen cache cleaning ever happened to it prior. Just trying to figure out what my next move now should be, get a new SIM card, or is a whole new phone needed?
I would first try another sim card to see it's related to the physical card or a carrier issue. Maybe try and borrow one from another network as well.
If that fails, try a factory reset.
If that fails, it's time to reach out to Samsung.
I tried a different SIM from a different phone from the same provider (on the same contract bill). But it wouldn't register, I even factory reset it prior to trying the other SIM. So I went and got a new one from the carrier, and problem solved! (First SIM card I've ever burned out without truly trying to)

Hi,
I've called HTC support and having my HOX returned for repair on the basis of the following 2 issues:
1) Wi-Fi, despite showing connected, is not able to connect to any web related connections via any of the apps that require it. If you type *#*#INFO#*#* and check the WiFi status there is an IP address but if you hit the 'Test' button it fails - all other devices in the house are fine during this time. Also I noticed, when this happens the phone is not pingable from the wireless network anymore (it is pingable when phone is working) - other threads here with similar symptoms but not one with a fix for me at least.
2) SIM card randomly restarts! Since the SIM card is PIN protected the phone will then not connect to the Service Provider as it is awaiting for the PIN number - as a person who regularly needs to be on call this is a big fail as the other day proved when I woke up in the morning and saw the phone not connected but instead asking for a PIN.
My question is, has anyone else had either of the above and did they manage to get them resolved after sending the phone back to HTC? Eg. did the phone come back without said issues or what is an utter waste of time?
I guess if HTC support are a waste of time - it's time I sent the HOX to the recycle centre and get £215 for it and get something else rather then beat on a dead horse...
Thanks for the answers in advance.

problem 1 is a (i think) the wifi fault many HOX are having. you can test it by pressing on the back between the camera and volume rockers. Your wifi receipting should go up
2. i also had this problem when is went in a few rollercoasters and also had a bad signal. simple solution > open your simcard tray and close it firmly again. it solved my problem! i think its a combination of both

Click to expand...
Click to collapse
on part 1:
I am 99% sure I don't have that Wifi fault because the phone already displays 4 sometimes even 5 bars when this happens and I am within 3 to 5 meters away from the AP too - I tried the squeze thingy and if anything it drops bars sometimes...what I did do though yesterday, is to install an extender and when it happens it flips over to the extended AP (if within proximity) and carries on working - I know this because I got a timeout page error and hitting refresh it worked immediately - ps when it happens you notice that small lag where 4-5 seconds go by for the page to load...happy to live with that.
on part 2:
I swapped out what I thought might be the offending SIM for another from a different provider, in hope that by doing so it eliminates the SIM from being at fault and in this case firmly closing the lid again - but it happens with both of the 2 SIM cards - I believe this to be an issue with the SIM tray not making enough contact with the SIM card (had this with an iPhone 3GS a few years ago and the Geniuses at the 'bar' swapped it immediately for another - I understand you have better chances of winning the lottery then HTC doing this though). Anyway both SIM cards work well with the old iPhone 4 I kept as a spare and now using as a daily driver since HTC are meant to collect. If they don't show up - it's recycling time... :crying: I really like the phone but I am not the type to live with such a shortcoming (eg. SIM disconnects)
Thanks for the reply.
Hello guys!
Hopefully you can help me with this one. Since 2 days ago, my GNex stopped being able to connect to my current carrier: Koodo (Telus' affiliate brand here in Canada). Now I initially thought it was a problem coming from the company's SIM card, and that it would've been relied to the Rogers shortage that occurred a couple days ago, but it wasn't. The symptoms are simple, no way to connect to the carrier. It happened randomly as I did not perform anything unusual with the phone, aside from connecting it via USB to my computer (which I often do). It does recognize that a SIM card is inserted and that Koodo is indeed a carrier, but when I click on it in my Network Operators menu, it tells me it can't connect and to try again later. When I click any other carrier, it says the same. So far here are the steps I took, with no success.
1. Removed both battery/SIM for a minute or more then rebooted. (Also made sure that 2G was off)
2. Called a Koodo tech guy who updated the SIM.
3. Went in store to try and put my SIM in a different phone, SIM worked fine.
4. Lady tried installing a different SIM card (her own), still same problem. Tried a brand new one, still not working.
5. Backed up my pictures and factory reset the phone. Same problem.
6. Took SIM out, and the phone does recognize there is not a SIM card and now the phone gives me the NO SIM CARD message at unlock screen.
7. Tried clearing the "Google Services Framework" cache, then update the phone but no update is found after multiple attempts.
8. Browsed the internet for hours then cried myself to sleep, hoping someone would help me out eventually.
By the way I'm using the same SIM in a different phone right now, and it works flawlessly. The phone was purchased on the Play Store and is factory unlocked. It is unrooted, and it was running 4.2.2 and now runs 4.2.1
Thanks!
Hi All,
I own a LG G3 for past 1 yr and 4 months. Every thing was fine until last month when I accidentally dropped my phone and the display cracked. Of course, touch did not work. So last week I went to an authorized LG service center to change the whole display (which involves the process of taking out the motherboard and fixing it with another display. This means the whole frame is changed). He did this process in front of me only. After the change, everything works well except for a weird WIFI problem which I never faced before the screen was replaced.
The WIFI would frequently connect and disconnect. Even in the search list, all the SSIDs would be shown occasionally and sometimes won't show up at at all. Note again, this happens with all the potential WIFI connections around, Not only with mine. In short, the WIFI search results list won't be stable.
Even if my WIFI shows up in the list and I try to connect it will show - "saved"/"disconnected"/"Disabled" status. And yes, occasionally my WIFI gets connected and internet starts working. But not for too long. Prolly the connection lasts for 5-10 mins or so. All my other devices connect using the same AP and so i don't really have a doubt on my router AP.
I visited the authorized service center again. Without even having looked at the problem he says motherboard might be the problem, and asked me to change it. Even if i persist him to have a look at the problem, he won't . My last resort is XDA
The ways I tried.
1. Factory reset.
2. Flashed roms 21A and 20P (from scratch, erased all data and caches). Still No joy.
3. Tried forgetting the network and connecting again.
4. Toggle WiFi on and off
P.S : I also have another problem of SD card getting unmounted automatically and an error message pops up as "SD Card removed unexpectedly. Please unmount SDCard before removing to prevent", but immediately a toast message comes as SD card inserted. xx.xx GB space available. This keeps on happening in a loop until SD Card wouldn't show up in File manager at all. But, this problem was there for a long time even before the screen was replaced unlike the WiFi
problem which occurred only after the screen is replaced.
I really don't know what exactly is going on with my phone. Please let me know if any of you are familiar with these problems and have solved it. Would really save a huge money for me
Recently purchased a new, unlocked S8+ and got a new SIM from Verizon. This was approximately 2 weeks ago. Zero problems up until this week. I have been on 4 flights this week - before each flight, the phone works great. When I land on the other end, Verizon LTE pops right up, varying numbers of bars as one would expect depending on arrival airport, just like it would normally when I have service and can do everything. However, nothing. No texts, no calling, no data. Tried toggling various things, resetting, nothing for a hour after that, all the while I've got 3-4-5 bars and I can see the data arrows lighting up like there is upload/download transfer.
Finally, I tried "reset network settings" as a last resort and immediately my phone works like a charm. It has happened another 3 times since - every time I have flown, with the exact same results.
All domestic flights. While I'm not a guru, I'm not a complete halfwit either - this is my 4th galaxy and it's definitely not something I'm doing or have ever had problems with before. I fly all the time and never a problem like this until this week. Checked APN, it's right. Checked software update - have most recent.
Any ideas? I'm desperate. Have searched literally everything I can think of and no one else seems to be reporting this problem, not to mention it's difficult to describe in a Google search. About at my wit's end having to re-enter wifi and passwords every day, relearn Bluetooth devices. Theres no other way to truly reset the mobile data settings and get my phone to work that I've discovered. Please, please help.
Eject SD card and remove sim, wait a min, reinsert cards. While the phone is on. Should reset just ur sim settings. Maybe
TL;DR
Moto Z2 Play - XT1710-07
The phone recognizes the SIM card but there is no signal (no service). Tried several things, including flashing a custom ROM. I'm considering buying a new motherboard and changing it myself, but first want to know if anyone knows more about this issue or has an idea/suggestion.
Edit: As an added bonus, something that only now I realized. Now when I charge it, it gets EXTREMELY hot. Like I-can't-even-use-it hot. I used to use the phone while charging all the time, but now I can't even hold it. Seems like the problem is when it tries go past 80% charge. It gets super slow, keeps trying and gets hot. Now I don't know if it's a software problem caused by the various flashings or if it's something that would remain even after swapping the motherboard.
Edit 2: I did a full discharge of the phone and recharged it while turned off. It seems to have normalized the battery problem
Edit 3: RIP. I tried to remove the screen before deciding about buying a new board. In the process, I ended up tearing the digitizer flat cable apart. Now I don't think it's worth it buying both a new screen and a motherboard.
The full story and things I've tried
My phone was working all nice and dandy until it stopped having signal/service. Wifi works normally, but anything related to the SIM card doesn't, like phone calls or mobile data.
A list of things I've tried somewhat in order (both of time and of complexity):
* My SIM in another phone: it works normally, so the problem is not the SIM itself
* Another SIM in my phone: it doesn't work, so the problem is definitely the phone
* Using the second SIM slot
* Changing "Preferred Network Type" between the available ones (4G, 3G, 2G, including Enhanced 4G LTE Mode on and off): this one and the next two items don't really make sense to me, since these options seem to be only related to mobile data (4G/3G internet) connection, not to phone calls which is also not working, but I tried them anyway
* Manually selecting the network: Errors with "Selected network unavailable" and, after trying to register for a while, toasts another error saying "Can't connect to the network, try again later"
* Manually selecting the APN: Tried both selecting between the two options available and manually adding an APN by googling the correct info for my carrier
* Simply booting into fastboot and restarting bootloader: a video on YouTube claimed that it was a temporary solution and that I'd need to do it every time it lost signal. But it didn't even work the first time
* Disabling CQATest and then restarting bootloader (and also clearing its data/cache and removing its permissions): a lot of videos on YouTube claimed this was a solution, including for other Motorola phones. Apparently CQATest prevents the phone from working properly in some scenarios. But I think only when you de-google your phone? Not sure. All I know is that it didn't work either
* Using the phone connected to the wall charger: I think this was another YouTube suggestion, and it actually worked for a few minutes. But I guess it was just a coincidence, as it never worked again
Now for some more... "forceful" attempts:
* Factory Reset: Not sure where I saw this suggestion, but it was pretty much the next logical step. Gathered courage, backed up all my data, etc, aaand... nothing again
* Flashing another ROM: Guess it was here at XDA that I read that it was a problem with Motorola's stock ROM. That, paired with my belief that it could still be related to CQATest being installed, I again gathered more courage to flash a custom ROM. I chose LineageOS and found out that it was no longer supported, but decided to install the last official release. I also read that the problem was the Pie modem firmware, so it all seemed to be going fine since the last official release is Oreo 8.1. I flashed it and BAM it worked! ... for a few minutes and never again. I messed around with LineageOS, tried some of the previous things again, but nothing.
Then, I tried to restore my TWRP backup but it didn't work. So I searched a bit more and downloaded the Stock Pie ROM, flashed it, and closed the bootloader. And then I realized the restore probably didn't work since my backup was made using Pie and my phone was on Oreo. Maybe some files/partitions were missing? Also, when I was creating my TWRP backups, I tried creating a full system image backup but it kept erroring. Only later I realized the problem was that the USB Drive was FAT32 and the full system image was bigger than 4GB. Oh, well, now I know.
So now that I'm with my phone pretty much back on square one, I take it to an authorized repair shop. The clerk said that it was a common problem, and that sometimes it could be solved "by software" and that they'd try that. The other option was to change the whole motherboard, which they didn't do because it was "not worth it" and "almost the full price of a new phone". After two days, my suspicions were confirmed: they didn't fix it with their "by software" attempt. At least I didn't have to pay anything.
When I got the phone back, I put the SIM in again and it showed the icon as if there was signal. But when I tried to call someone, the signal disappeared again. I tried searching a bit more, went through all pages of Q&A here at XDA forums and there were like 3 posts regarding loss of signal. All without any response. On YouTube, I found some videos offering a suspicious .bat file. Upon inspection, it merely erased the modemst1 and modemst2 partitions and then wiped user data and cache. I tried it, nothing to lose. Also didn't work.
Now I'm contemplating a few options:
By watching some disassembly videos, I saw that, when opened, the phone has some parts that act like antennas. I thought that maybe those were not properly connected to the board? Maybe they got dislodged during a fall? Seems unlikely tho, since they are screwed in. I searched for a new motherboard to buy and it's a reasonable price. But I'm afraid it'll have the same problem (or develop it in a short time) since I can't find anywhere what the true cause of the problem is.
Another option is to just give up, buy a new phone and use this one as if it was a "small tablet" lol
So, do you guys have any other suggestions or ideas as to what might be the problem? Maybe a tip like "solder a wire to this spot to create a make-do antenna"? I don't really know where else to search.
If not, thanks anyway for those who read it all
